Abstract
An electrode catalyst comprising a lead dioxide electrically deposited layer, the layer having particles containing .beta.-lead dioxide powder dispersed therein, and a method for producing the electrode catalyst are disclosed. The particles contain .beta.-lead dioxide powder and optionally an electrolytic cocatalyst selected from PTFE, agar, gelatin, a perfluoro ion exchange resin and the like. The present electrode catalyst is useful for production of ozone by electrolysis of water and for production of peroxides by electrolysis of aqueous solutions.
